I think there's something written down somewhere that they will change usernames, but only for very real reasons, it's unlikely that they'll change it in all honesty.

And as for the ban, if it's your first one, it'll be 30 days, second ban, 45 days, 3rd ban is perma.

Actually,

1st Ban - 30 days

2nd Ban - 45 days

3rd ban 60 days

4th Ban - Permanent Ban (Fo' evarr, niggz)

But yeah, I've seen 'Delete/Rename my account' threads around before, and the admins usually won't change your name because of your profile will keep your original name, and apparently it's huge hassle to delete and modify any user's account, and ultimately, if one person gets their name changed/account deleted, everyone else will say "Why can't you let ME change MY account?".

If you're deleted, they would have to delete every one of your posts, threads, and contributions. Otherwise, if 500 people change their accounts, that's a lot of posts.And a lot of dead links if you were to click on the abandoned profiles' username.
